Hello Everyone,
I'm trying to get the EMUI 9.1 update on my P20 Pro (Canadian Version) and the system download the updates and it reboot, and gets back to the previous state 9.0 and it asks to upgrade again.
I tried upgrade using the HiSuite and also gets the same issue.
Do you guys know if with the bootloader unlocked and Magisk Manager installed on my boot partition affect this upgrade ?
Thank you
No

Hey i have p20 pro 6/128 which today i glt the pie 9.0.
The matter is that my phone is rooted and has unlocked bootloader. I downloaded the update and got in twrp for flashing and got errors.
Should i lock again the bootloader to update the phone ?

Or i can find on my phone files the update zip and flash it through the twrp manually?
Hi All,
As you know they already released the Official Android 9.0 Pie for Huawei P20 Pro in EU.
I have the previous version of Android 8.1 CLT-L29.
My devices is:
-Rooted
-Bootloader unlocked.
Can I update via OTA to Android 9.0?
Is there any problem during the upgrade?
Will be still rooted and bootloader will be still unlocked?
If not what is method to do upgrade and still have a Root?
Thanks for your help!
You need to flash stock recovery first.
You will not continue to rooted.
Your bootloader will remain unlocked
Thanks for your kind answer.
Do you think should I update to 9.0 or should I stay with the previous version?
I am not that sure about the root process at the moment and I don't want to loose it.
I don't think there are that many new noticeable features. EMUI looks and behaves pretty much the same.
Hi,
Did anyone manage to downgrade from 9.1.0.311 to 9.0 or 8?
When I am trying to rollback to 9 in Hisuite it doesn't work (TWRP says No OS installed).
Eventually, I would like to downgrade to 8.1/8.0/
(It's a device with unlocked bootloader, and I would like to keep it unlocked).
Thanks!
I was able to downgrade to 8.1 from 9.0.0.286. was using TWRP and cannot update via OTA. I use a modded version of hi suite and use rollback option. before reboot, flashed the recovery from .195 firmware via fastboot and hold volume up while turn on.. to my surprise it apply the update and send me back to 8.1.
The bootloader still unlocked after this. that's was strange.

I've relied on ota updates on my P20 Pro but it still hasn't received the android 10 update, even though my provider is meant to have pushed it out. Its unlocked, so I should be able to install any version for my model CLT-L09 (C782). Is it possible to download this update and install it through the e-recovery menu?
Hi. Short time ago i've bought p20 pro (CLT-L29C432), downgraded EMUI to 8.1 from 10.0 and then flashed custom rom, based on EMUI 8.0 for another model (not 432).
Ofc phone caught bootloop...
Installed with fastboot "Huawei P20 Pro CLT-L29 Charlotte-L29C 8.1.0.128a(C432) Firmware Android8.1.0 EMUI8.1.0 05015BGR" and few other based at 8.1.0 and 8.0, but also bootloop.
I can install twrp, get into it, but nothin more - only bootloop.
Maybe some1 can help with working instruction for solving this problem. Thank you for answers.
Have you unlocked the bootloader? If yes message me...its actually easy (if the bootloader unlocked)...
